Scientists believe Mars has lost most of a once-far-thicker atmosphere. But molecular composition data supporting that hypothesis have suffered high levels of experimental uncertainty: Error bars in graphs of data from the Red Planet often exceed the measured values themselves. Measurements from NASA’s Curiosity rover now bolster the atmospheric loss idea by greatly reducing the uncertainty, according to researchers led by the space agency’s Paul R. Mahaffy and "; $("#ERA_RC").html(contextualDefault); } }); var era_rc1 = {StyleId: '1',ERADomain: 'cen.firstlightera.com'};
